How To Fix Warped Doors

A warped door can be a real nuisance in any home, causing difficulties in closing and opening, permitting air drafts, and even inviting unwanted pests. If you’re grappling with this issue, you’re in luck! This comprehensive guide will walk you through everything you need to know about fixing a warped door.

Identifying the Problem

Before you can fix a warped door, you need to pinpoint the exact location of the warp. This could be at the top, bottom, or side of the door.

Visual Inspection

Begin by visually inspecting the door. Look out for gaps between the door and the frame, as well as any bends or curves on the door’s surface.

Physical Inspection

Following the visual inspection, try closing and opening the door multiple times. If the door drags or doesn’t latch properly, it’s likely warped.

Tools Needed to Fix a Warped Door

To fix a warped door, you will need a few tools. These include:

  • Two Sawhorses: These will support your door while you work on fixing it.
  • Screwdriver: This will be used to remove all hardware from the door.
  • Sandpaper: You will need this to sand down the warped parts of the door.
  • Towels: These will be used in the process of straightening the door.
  • Wood Varnish: This will serve as your sealant, preventing the wood from warping again.
  • 50-lb sandbag or something of equal weight: This will be used to flatten the warped door.
  • Paintbrush: This will be used to apply the wood varnish.

Step-by-Step Guide to Fixing a Warped Door

Now that we have the tools and have identified the problem let’s dive into the step-by-step process of fixing a warped door.

Step 1: Remove the Door

Start by removing the door from its hinges using your screwdriver. Place the door on your sawhorses for support. Make sure the warped side is facing upwards.

Step 2: Sand the Door

Next, use your sandpaper to sand down the areas of the door that are warped. Pay close attention to the top and bottom of the door, as these are often the most affected areas.

Step 3: Flatten the Door

After sanding, it’s time to flatten the door. For a slightly bowed door, place your sandbag or an object of equal weight on the warped area. Leave it there for 24 hours, or until the warp is completely gone.

For a badly warped door, wet your heavy towels and lay them across the warped area. Each day, re-wet the towels and add five to 10 pounds of weight to the door until it’s completely straight.

Step 4: Seal the Door

Once your door is dry and straight, apply a coat or two of wood varnish to the whole door using your paintbrush. This will seal the door and protect it from further warping.

Causes Behind Warped Doors

Before diving into the solutions, it’s essential to understand why your doors are warping in the first place.

Heat and Moisture

The most common culprits behind warped doors are heat and moisture. Doors, particularly wooden ones, are susceptible to fluctuations in temperature and humidity levels. Constant exposure to these elements can cause the door to expand, contract, and eventually warp.

Poor Installation

Sometimes, a warped door could be the result of improper installation. If the door was not correctly fitted into the frame, it could eventually buckle under pressure and warp.

Structural Settling

Houses, especially older ones, tend to settle over time. This settling can cause the door frames to shift, leading to a warped door.

Avoiding Door Warp

Here are some helpful tips that will keep your door from warping:

  1. You should always avoid making adjustments to your food when there is a significant change in weather.
  2. Make sure that you use sealants that keep out moisture from your door. Since exterior doors are most likely to get warped, use polyurethane door sealant to protect them.
  3. Apply regular polish on your door (twice a year).
  4. Always go for fiberglass as your exterior door material instead of wood.

Bottom Line

Warped doors always leave an opening after it is closed. Protecting your doors from warping is essential to keeping your house safe from pest invasion and all kinds of burglar activities. You can start today by protecting your door from bad weather conditions. And if you notice any warp on your door, go through the simple steps to get it fixed in no time.
